L-LYSINE-ALPHA-N-FMOC, EPSILON-N-T-BOC (13C6; 15N2) is an isotopically labeled, protected lysine amino acid derivative featuring an α-amino group masked as an Fmoc carbamate and an ε-amino group masked as a tert-butoxycarbonyl (t-Boc) carbamate, with the side chain terminating in a protected primary amine. The molecule contains both a free carboxyl group and two carbamate-protected nitrogen functionalities, and the (13C6; 15N2) labeling indicates incorporation of heavy isotopes within the lysine backbone and/or side chain consistent with lysine's carbon and nitrogen content. In peptide synthesis workflows, this doubly protected, isotopically enriched building block is used for stepwise assembly and for preparing labeled peptides or amino acid-containing conjugates where stable isotope tracking or mass spectrometric distinguishability of lysine residues is required.
